SYDNEY – Tens of thousands of tourists, scientists and amateur astronomers from around the world waited anxiously across tropical northern Australia on Tuesday to find out whether the clouds will part in time to see a total eclipse of the sun.
Forecasters were predicting cloudy skies around dawn Wednesday, when the moon will pass between the sun and Earth and plunge a slice of the continent's northeast into darkness. Many worried that they will miss a rare chance to view the celestial phenomenon.
"There will be breaks in (the clouds), but it's just a matter of the luck of the draw whether you get a break at the right time," said Queensland state Bureau of Meteorology forecaster Andrew Mostyn. "It's a bit of bad luck."
The eclipse will cast its 150-kilometer (95-mile) wide shadow starting at dawn in Australia's Northern Territory and then cross the northeast tip of the country before swooping east across the South Pacific, where no islands are in its direct path. A partial eclipse will be visible from east Indonesia, the eastern half of Australia, New Zealand, Papua New Guinea and southern parts of Chile and Argentina. Totality — the darkness that happens at the peak of the eclipse — will last just over two minutes.
Among those sweating out the forecast was U.S. astronomer Jay Pasachoff, who traveled to Australia in hopes of viewing his 56th solar eclipse. Pasachoff, an astronomy professor at Williams College in Massachusetts, and a team of about 50 scientists and students have fanned out across the region to improve the odds that at least some of them will see the eclipse. The group is planning to study the sun's corona, the glowing white ring around the sun that is only visible during an eclipse.
Despite the anxiety over the weather and the long journey to get there, Pasachoff said he wouldn't miss it.
"Just imagine you were a heart surgeon and someone actually told you you could look inside a human heart only for two minutes, and only if you went halfway around the world," he said. "You would do it."
Some Queensland hotels have been booked up for more than three years and more than 50,000 people have flooded into the region to watch the solar spectacle, said Jeff Gillies, regional director of Queensland Tourism.
Skygazers are planning to crowd beaches, boats, fields and hot air balloons to watch the event. Fitness fanatics will race in the Solar Eclipse Marathon, where the first rays of the sun re-emerging from behind the moon will serve as the starting gun. Some have already been partying for days at a weeklong eclipse festival.
Scientists will be studying how animals respond to the eclipse, with underwater cameras capturing the effects of sudden darkness on the creatures of the Great Barrier Reef.
"It's an unknown with how they'll react," Gillies said. "A little bit of flora and fauna confusion, I would imagine."
The last total solar eclipse visible in Australia was 10 years ago, in the South Australia Outback.
